WILLIAM B. ARNOLD, OF NORTH ABINGTON, MASSACHUSETTS.

MACHINE FOR RASPING PEGS.

SPECIFICATION formingpart of Letters Patent No. 245,269, dated August 9,1881.

Application filed June 13, 1881. (No model.)

To all whom 1t may concern Be it known that I, WILLIAM B. ARNOLD, ofNorth Abington, of the county of Plymouth and State of Massachusetts,have invented a new and useful Improvement in Machinery for Rasping Pegswhen projecting into the footreceiving space of a boot or shoe; and I dohereby declare the same to be described in the following specification,and represented in the accompanying drawings, of which- Figure l is aside elevation, Fig. 2 a front view, Fig. 3 a longitudinal section, andFig. 4 a transverse section, of a peg-rasping machine containing myinvention. Fig. 5 is a longitudinal section of a heel-rasper-carryingarm, with the rasper and its operative shaft and gear, to be hereinafterdescribed.

The nature of my said invention is duly set forth in the claimshereinafter presented.

In the drawings, A denotes the standard for supporting the carrying-armB of the toerasper G, such arm being journaled in the upper part of suchstandard, so as to be capable of being revolved horizontally, aset-screw, 8, being used to clamp the arm in position. Within the saidarm, which is tubular, is mechan-- ism for revolving the toe-rasper,such mechanism consisting of bevel-gears a b, an inclined short shaft,0, two bevel-gears, d e, and a vertical shaft, f, provided at its lowerend with a beveled gear, 9, all being arranged as represented. The saidgear 9 engages with another bevel-gear, fixed on a shaft, h, arrangedhorizontally in the standard and in suitable bearings therein, suchshaft It being provided at one end with a fly-wheel, z.

The standardAis a hollow column,provided near its upper end with aspherical projection, 70, within which is a chamber, Z, having twolateral mouths or openings, at n, arranged to lead out of it in manneras represented. Within this chamber (which I term the pulley-chamher)and fixed on the shaft his a pulley, 0, and a bevel-gear, p, the latterbeing made to engage with the gearg at the lower end of the shaft f.Furthermore, there projects from the part is, concentrically with theshaft h, a tubular journal, q, to which there is applied, as shown, thearm D, carrying the heel-rasper E I and its operative shaft 1", arrangedin such arm,

as set forth. At its lower end the shaft 1 has fixed to it a bevel-gear,s, to engage with another bevel-gear, t, fixed on the pulley-shaft h,and arranged as represented. The arm D is to turn upon the journal (1 inorder to enable an attendant to adjust the arm into either a vertical orsuch an inclined position as may be most convenient for him, whether forpackage or use of the rasping-machine. This arm D, at its lower part, isfurcated, as shown, and to each prong a of it there is a bearing, '0, tofit to the journal, the two arms being provided with a screw, 10, forclamping them to the journal,so as to enable the arm to be revolvedtherein with the necessary friction.

Thelower partof the standard is perforated or open, as shown at w, toreceive a drivingwheel, y, and its operative pedal 2, the latter beingplaced alongside of the said wheel and pivoted to an arm, F, projectingfrom the standard. The wheel-shaft is to be properly supported by thestandard in order for the pedal to be suitably connected with the wheel,which it is by means of a crank-pin extended from the latter into a slotformed lengthwise in the pedal. An endless belt, G, applied to theperiphery ofthe driving-wheel, passes into and out of the pulley-chamberof the projection 75 by its months at a, and partly around the peripheryof the pulley 0. On an attendant applying his foot to the pedal, andmoving it, the driving-wheel will be put in revolution, so .as to causethe belt to revolve the pulley and its shaft, and thereby simultaneouslyput in action the mechanism for operating each of the heel and toeraspers.

B y havingthe driving-wheel and treadle and driving-belt and pulleyarranged within the standard in manner as represented, the machine isrendered very compact, and by pro- 0 viding the standard with thetubular journal, and having the heel-rasper arm constructed and appliedas explained to such journal, further advantage, as hereinbefore stated,is obtained. I

What I claim as my invention is as follows,

viz:

1. The supporting-standard A, having to its part It the tubular journalq and the pulleyshaft h extended through it, and provided with thebeveled gear t, in combination with the heel-rasper-carrying arm D,adapted to turn on suohjournal, and furnished with the raspershaft andits bevel-gear, to engage with the aforesaid bevel-gear t, all beingarranged and adapted to operate substantially as set forth.

2. The heel-rasper-carrying arm D, tubular and furcated, and providedwith journal-bear ings and a clamp-screw, all substantially as setforth, in combination with the tubular standard A, having to its part Itthe tubular journal 1, to enter the said journal-bearings, as specified.

3. lhe standard A, furnished with the pegrasping mechanism, and providedwith the pulley-chamber and its lateral mouths, and with the opening forreception of the drivingwheel and its pedal,and with the arm forsupporting the said pedal, all being substantially as set forth. 7

4. The standard A, provided with the pegrasping mechanism, and with thepulley-chamber and its tubular mouths, and with the opening and arm forreception and support of the driving-wheel and its pedal, in combinationwith the said driving-wheel and pedal, and the pulley and its shaft,arranged in such standard, as set forth.

5. The standard A, provided with the pulley-chamber and its lateralmouths, and tubular journal, arranged as described, in combination withthe driving-wheel, pedal, endless belt, pulley, and pulley-shaft,arranged in the standard, and with the heel-rasper-carrying arm, adaptedto turn upon the said tubular journal, and with the pulley-shaftprovided with mechanism for aotuatin g the heel-rasper,

all being arranged and applied essentially as v specified.
